GUIDE-BRACKET AND WEDGE FOR SLIDING DOORS.

SPECIFICATION forming part of Letters Patent No. 530,182, dated December4, 1894.

Application filed May 24,1894. Serial No.5l2,3'73. (N0 model.)

.To all whom it may concern:

Be it known that I, WILLIAM W. HOLMES, a citizen of the United States,residing at Ohicago, in the county of Cook, State of Illinois, haveinvented certain new and useful Improvements in Guide-Brackets andWedges for Sliding Doors; and I hereby declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawings, in which- Figure 1, is a front view, inelevation, of a guide bracket and wedge embodying my in vention, andportions of a door and sill to which the wedge and bracket are attached.Fig-2, is a side View of the same, in elevation, the portions of doorand sill being in section. Fig. 3, is a top View of the devices, theportion of the door being in section and the position of wedge andfastening bolts being indicated by dotted lines. Fig. 4, is a detached,rear perspective view of the guide bracket; and Fig. 5, is a detachedperspective view of the bracket wedge.

Like symbols refer to like parts wherever they occur. v

My invention relates to the construction of guide brackets and wedgesfor securing the bottoms of sliding doors, and while of generalapplication to all suspended sliding doors, has been especially devisedfor use on the doors of freight cars.

The usual construction of guide brackets, or those commonly employed forsecuring the bottom of sliding doors for cars, is of a character whichpermits of the removal or displacement of thebracket to such an extentas will permit the door to be swung outward from the car and accessobtained without destroying the seal used to secure the car door whilein transit. To overcome these objections and provide a simple guidebracket which shall be secure against unauthorized removal ordisplacement while the car is in transit, I form the bracket with twosets of fastenings one of which is by preference a threaded bolt or lagscrew integral with and projecting from the back of the bracket so as tobe secreted when the bracket is secured to the car, and another of whichmay be and preferably is, a through bolt the hole for which, in thebracket, is in the rear of the wedge channel so as to be covered by thewedge and thereby concealed when the door is closed and the wedge inposition; and a guide bracket so constructed embodies the main featureof my invention.

There are other minor features of invention, all as will hereinaftermore fully appear.

I will now proceed to describe my invention more fully so that othersskilled in the art to which it appertains may apply the same. In thedrawings A indicates a portion of the side or sill of acar-or otherstructure to which the guide bracket B is attached, and C the wedgewhich co-aots with the guide bracket and is secured to the door D. Thewedge and guide bracket are usually malleableized castings, but may beof any suitable material, or produced in any desired manner. The guidebracket if desired may be of the usual or any approved general patternso that when in position on the car it may not present any unusualappearance, and it may therefore have the usual through bolts b, b,secured by the exposed nuts 17', b which will support the bracketagainst heavy blows. I provide the bracket, however, at its back, withsecret fastenings, the lower of which maybe a simple projection orprojections to enter the sill or side of the car and prevent therotation of the bracket when the bolts b b are removed-but saidprojection is preferably a single one in the form of a lag screw 1 castintegral with and projecting from the back of the guide bracket. Abovethe lag screw 1 and formed in an ear or flange 2 which stands above thebottom of the wedge channel 3 at the back of the bracket, is a bolt hole4? (see Fig. 4) for the passage of a secret bolt 4. having a button head5, and whose nut6is secreted in the wedge channel 3 of the bracket so asto be covered by the wedge 0 when the door is closed. If desired thevertical lip7 of the guide bracket may be hollowed out centrally as at 8(Fig.3) which will facilitate the application of nut 6 to bolt 4 inapplying the guide bracket to the sill A, without materially weakeningthe guide bracket or preventing it from properly c-o-acting with thewedge (J.

The fastenings for the wedge as heretofore applied have developedmaterial weakness when in use, and to overcome this objection I providethe angle plate 9 which supports or carries the wedge G with a series oftransverse ribs 10 (or equivalent projections such as lugs or points)which enter the bottom edge of the door, and support the wedge and angleplate against lateral force, and I then secure the angle plate above bya series of through bolts 11 well away from the edge of the door. Forthe purposes of this specification I have illustrated the guide bracketin conjunction with a wedge projecting downward from the under side ofthe door, as such a construction is not only admirably adapted toconceal the secret fastening of the guide bracket but also reduces theprojection of the fixtures from the side and renders them less liable tobe struck and knocked oft-but it will be evident to one skilled in theart that a laterally projecting wedge may be employed if desired, thewedge channel 3 of the bracket being correspondingly widened to receivethe wedge.

The construction being substantially such as hereinbefore set forth, theguide bracket will be secured to the sill Aor other supportby screwingthe lag screw 1 into the sill and bringing the bracket to its verticalposition after which the button head bolt tis passed through the sillAand the nut 6 screwed upon the end which projects into wedge chan' nel3. The exposed bolts b b and nuts I) b may then be applied in the usualmanner.

3 cut, is-

1. A guide bracket, having a wedge channel, a bolt orifice at the backof the wedge channel, and a projection at the back of the bracket belowthe wedge channel, substantially as and for the purposes specified.

2. A guide bracket, having a wedge channel, a perforated car at the backof the wedge channel, and a lag screw at the back of the bracket,substantially as and for the purposes specified.

3. A guide bracket wedge, having an angle plate base providedwith aseries of transverse ribs; substantially as and for the purposesspecified.

In testimony whereof I'affix my signature, in presence of two witnesses,this 2d'day of May,

WILLIAM W. HOLMES. Witnesses:
